OIL BURNER.

Application filed Ju1 a1,

Brooklyn, res ectively, in the counties of Lebanon and l ings,respectively, and States of Pennsylvania and New York, respectively,have invented certain new and useful Improvements in Oil Burners, ofwhich the following is a specification.

The invention relates to oil burning apparatus in which the oil isatomized, for example, by low pressure air and discharged for ignitionin a highly atomized state thru a suitable tip.

It has for its object aburne'r having means for more efiicientlyatomizing the oil and mixing the same with a gaseous medium, moreparticularly in two stages; and to afford, also, a burner of simple anddurable construction in which the flame isadjustable thru movement ofthe said tip; and wherein, furthermore, the oil supplying nozzle isconveniently removable for cleaning and so constructed as to be readilycleaned.

The nature of the invention, however, will best be understood whendescribed in connection with the accompanying drawings, in which- Fig. 1is an elevation of the burner.

Fig. 2 is a plan thereof.

-Fi'g. 3 is a longitudinal section burner.

Fig. 4 is a fragmentary section of the sleeve for introducing theatomizing medium.

Similar characters of reference designate I corresponding partsthroughout the several views.

Referring to the drawings, the burner i shown to consist of a suitablecasing havin a vertically disposed chamber 10 through which theatomizing gaseous m'edium,as air under the requisite pressure, is to besup plied, the volume of same being controllable by a suitable valve asthe butterfly valve 11 provided therein. The upper portion of the casingcomprises a body 12 afi'ording a hori-- zontally disposed chamber whichis o n to the vertical-chamber 10 and is provide with thru the.

an inlet 13 and outlet 14 axially disposed therein. Fitting coaxiallywithin the body. 12 is a sleeve or tubular member 15 having openings 16to afford communication with the chamber12 and thru which the gaseous1923-; Serial No. 654,839.

atomizing medium may enter. Thissleeve is secured to the inlet 13 andits forward end projects beyond the outlet 14:, terminat- 4 111g in aconstricted and flarin An intermediate portion of the s eeve is alsoconstricted, as at 18, to formfla Venturi nozzle in conjunction with theoil supply nozzle 20 which is mounted coaxially within said sleeve, thenozzle having an axial bore 21 extending from endto-end and providedwith radial outlets22 at the Venturi end. The air velocity isconsequently increased 'at this point, its at'omizing efl'ect enhancedand an intimate mixture therewith of the oil supplied thru the radialoutlets 22 is secured. The bore of the nozzle is closed atthis endpreferably by api-pe plug 23; and, similarly, the opposite end of thebore is closed by a pipe plug 24 fitting in the head 25 of the nozzle.The head 25 serves also to seal the inlet 13 of the body 12 and [isprovided with a duct 26 communicating with the bore 21, the formerhaving suita le means "for outside connection to supply oil to thenozzle. By this expedient, the nozzle with head is convenientlyremovable; and by unscrewing the plugs 23 and 24 from the ends thereof,the bore is open thruout and ma readily be cleaned when this becomesnecessary.

Surrounding theforwardend of the sleeve 15 and havinga sliding fit witha portion of the same and with the body portion 12 to closesubstantially the outlet 14 of the latter, is an adjustable tip 30,tubular in form and having an opening 31 at its outer end coaxial. withthe flaring outlet 17, the

wall of the tip and the outer end of the sleeve being separated andforming a tapering annular'space between the same. The tip, moreover, isprovided with openings 32 to afi'ord communication between theinteintimate mixture of oil and airproduced is.

' rior of the body'portion and the said tapercarried forward by the airdelivered thru the annular space to the outlet 31 of the tip where it isfurther atomized and mixed and discharged for ignition with a blowingeffeet, the swirling motion heretofore referred sleeve an the outlet 14of the body portion. To effect this reciprocation of the tip, a yoke 35is arranged over the burner appa'ratus with its arms at either sidethereof,

and the ends of said arms are secured to the tip 30 at diametricallyopposed points. Thru an opening 36 in the back of the'yoke is inserted astud 37 which is threaded into the head 25 of the oil nozzle, said studcarrying a collar 38 within the yoke; and at its outer end a hand wheel39 is adapted to shoulder against the back of the yoke. so that inturning the said hand wheel, the yoke is correspondingly advanced orretracted to adjust the tip 30. In order to limit the extent of thereciprocation, the arms of the yoke are provided with open notches orslots 40 in the upper edges there of and into which fit correspondingpins 41 secured in the body portion 12, the same acting as stops thruengagement with the respective sides of the notches.
